Flying disc equipped with V-shaped lifting blades

ABSTRACT

Flying disc equipped with V-shaped lifting blades is a flying disc which is equipped with several V-shaped lifting blades on the top. Because of the extra lifting force of the equipped V-shaped lifting blades when turning it can fly higher than a regular Frisbee. It can be turned either clockwise or counter-clockwise to produce extra lifting force to fly higher. Therefore a left-handed player and a right-handed player can play with the same flying disc equipped with V-shaped lifting blades.

THE BACKGROUND OF THE INVENTION

When a Frisbee is thrown forward it flies horizontally forward and the altitude of its flight depends upon the angle of the throw and the lifting force of the dome-shaped Frisbee due to its aerodynamic mechanism of an airfoil like a plane's wing. A flying disc equipped with V-shaped lifting blades can fly higher because of the extra lifting force of the equipped V-shaped lifting blades which act like helicopter's rotors in addition to the lifting force of its airfoil dome shape.

THE BRIEF SUMMARY OF THE INVENTION

Flying disc equipped with V-shaped lifting blades can fly higher than a regular Frisbee because of the extra lifting force of the equipped V-shaped lifting blades in addition to the lifting force of dome-shaped flying disc due to aerodynamic airfoil mechanism.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 is the perspective view of a flying disc equipped with V-shaped lifting blades which are installed on top of the fenestrated flying disc body.

FIG. 2 is the perspective view of a fenestrated flying disc body.

FIG. 3 is the perspective view of V-shaped lifting blades.

THE DETAILED DESCRIPTION OF THE INVENTION

Referring now in detail to the drawings numeral 11 of FIG. 1 is a flying disc equipped with V-shaped lifting blades. Numeral 12 of FIG. 1 and FIG. 2 is the fenestrated flying disc body. Numeral 13 of FIG. 1 and FIG. 3 is V-shaped lifting blade. Numeral 14 of FIG. 1 and FIG. 2 is the vent of fenestrated flying disc body 12. V-shaped lifting blade 13 is a little bit wider and a little bit shorter than vent 14. Numeral 15 of FIG. 1 and FIG. 2 is a built-in socket for installing V-shaped blade 13. Built-in socket 15 of FIG. 1 and FIG. 2 is positioned at the center of inner side and outer side of vent 14. Numeral 16 of FIG. 2 is central opening of built-in socket 15. Numeral 17 of FIG. 3 is the pivot of V-shaped blade 13. The diameter of central opening 16 is bigger than that of pivot 17. Pivot 17 of FIG. 2 is inserted into the central opening 16 of FIG. 2. Numeral 18 of FIG. 1 and FIG. 3 is designated as the right wing of V-shaped blade 13. Numeral 19 of FIG. 1 and FIG. 3 is designated as the left wing of V-shaped blade 13. Right wing 18 of V-shaped blade 13 and left wing 19 of V-shaped blade 13 are identical. After inserting pivot 17 of FIG. 3 into central opening 16 of FIG. 2 with both right wing 18 and left wing 19 pointing upward, the V-shaped lifting blade 13 is installed onto flying disc body 12 as illustrated in FIG. 1. Because V-shaped lifting blade 13 is a little wider and a little shorter than vent 14, right wing 18 and left wing 19 of FIG. 1 and FIG. 3 will stay on the top of vent 14 of FIG. 1 as illustrated in FIG. 1. When flying disc equipped with V-shaped lifting blades 11 turns clockwise, left wing 19 will be pushed and tilted downward by the wind to tilt upward right wing 18, and right wing 18 also will be pushed upward by the wind to thrust the wind beneath it to provide extra lift to the flying disc equipped with V-shaped lifting blades 11. When flying disc equipped with V-shaped lifting blades 11 turns counter-clockwise right wing 18 will be pushed and tilted downward by the wind to tilt upward left wing 19 which also will be pushed by the wind to tilt it upward to thrust the wind beneath it to provide extra lift to the flying disc equipped with V-shaped lifting blades 11. Therefore a right-handed player and a left-handed player can play with the same flying disc equipped with V-shaped lifting blades 11.
